Dynamic miniature lighting system with low correlated colour temperature and high colour rendering index for museum lighting of fragile artefacts

Abstract

Illumination of fragile and irreplaceable historical objects exhibited to the public presents challenges with regards to: good colour rendering, low photochemical degradation of sensitive materials and general energy consumption. We present a dynamic tri-colour LED lighting system for illumination of historical artefacts in display cases at museums and other exhibitions, which can replace 3-5 Watt incandescent light bulbs with a correlated colour temperature (CCT) from 2000 K to 2400 K. The solution decreases the energy consumption by up to 80 %, while maintaining colour rendering indices (Ra) above 90 and important special colour rendering indices R9 between 50 and 90, while decreasing the level of harmful short wavelength radiation by between 20 - 30 %.
